Re: How do I monitor for the message "Indicator variable required" in the following statement?

From the manual...

"The IFNULL function is identical to the COALESCE scalar function with two
arguments."

Where did you use it? Are you perhaps missing PTFs?

COALESCE worked.

Thank you all.

Why do you believe IFNULL() is not usable?

where WBPPN = :slptno

and wbco = :slco

and wbwhno = :slloc;



In sql scripts, I have used IFNULL, however, IFNULL is not usable in a
RPG program.



This is a 7.2 system.
